These are my instructors additions:

If the whole excel approach sounds confusing then please help in solving the original question. That way I can use that method in solving the question the way my instructor expects.

In class today I was given an extension on this problem.

I also found that the free body diagram that I was using was a little complicated and the only forces acting on the handle is the applied force and the force caused by the spring. I'm a little confused in how to find the force caused by the spring and which [tex]\Sigma F=0[/tex] and [tex]\Sigma M=0[/tex] equations to use.
